Help me understand curves in VituixCad

[vlad99]

Hi, i'm new to speaker building and wanted to understand a bit more about curves in vituixcad, to be precise i have this tang band w6 2100 and if i put it into a closed box of about 16 liters ( the vas of the driver is about 16 liters) i get this response ( black line in the SPL graph), but if i look at the SPLmax line (the light blue one in the SPL graph) i get a big spike at around 62 Hz, why is that? is something related to box resonance, xmax?

is something related to box resonance, xmax?

Apparently so. I found this on the diyAudio forum posted 4 1/2 years ago:

"Total SPL max curve (cyan) is based on Xmax only at the moment."

"* Total SPL Max curve (cyan) limited with Pmax."

Just to get started.
